A Study On The Specimen Of Ellobium Chinensis From Deshou Palace Site About T1024 Excavation-squares In Hangzhou

Deshou Palace Site in Hangzhou is an important royal palace in the Southern Song Dynasty.In the GJCT1024 exploration site,a large number of specimens of Ellobiidae were excavated.According to the identification and study,the specimens of Ellobium chinensis unearthed from the Deshou Palace site should be native to the South China Sea,which is a special marine product transported to the royal palace of the Southern Song Dynasty through long distance.The measurement results showed that the samples of this batch of Ellobium chinensis were mainly medium-sized and large-sized,and the larger body with abundant meat resources should be taken as the edible object after people' s conscious selection.The damage location,damage degree and preservation state of Ellobium chinensis specimens had certain rules.Through observation,statistics and experimental analysis,it was found that the damage characteristics of shell top should be that people used scissors to cut the shell top before cooking Ellobium chinensis in the Southern Song Dynasty.This processing method of cutting the shell top before cooking is consistent with the traditional snail eating method of modern coastal residents in China.It is a snail cooking method commonly known as “tail cutting” in China,and empirical materials are found from archaeological work.The specimens of Ellobium chinensis unearthed from the Deshou Palace site are the largest batch of marine Ellobiidae specimens identified in China' s archeology at present.It provides very important research data on the political status and economic circulation of Lin' an(today' s Hangzhou),the capital of the Southern Song Dynasty,as well as fishery production and royal diet customs in the Southern Song Dynasty.The content of this paper is mainly divided into six parts:The first part is the introduction.This paper introduces the research situation of mollusc archaeology and Ellobiidae remains in China,and introduces the current animal archaeology research work at the Deshou Palace site.This paper describes the research methods and significance.The second part introduces the source of research materials and the method of specimen extraction.Describes the historical background and excavation of the Deshou Palace site;This paper describes the extraction and cleaning process of materials.The third part is specimen identification and specimen description.Animal species identification was carried out on the unearthed Ellobiidae specimens from the aspects of size measurement,morphological identification and description.Combined with mollusk reference data and existing specimen database,the specimens unearthed from T1024 exploration site in Deshou Palace were identified as Ellobium chinensis.The minimum number of individuals is 203.A total of 159 specimens with relatively complete shell were preserved and described in three categories: large,medium and small according to the measured data.The fourth part is to carry out the research on the relationship between Ellobium chinensis specimens and human cooking behavior information.The analysis found that the Ellobium chinensis unearthed from the site were mainly medium-sized and large,and humans had selected the size of the Ellobium chinensis.The damage characteristics of shell top have high similarity.By using different tools to test the damage of the shell top,it is shown that the damage of the shell top should be caused by the conscious cooking and processing behavior of human beings,and should be the regular damage caused by the shear of the shell top by human beings.This cooking and processing method of cutting the shell top of the snails is still preserved in the consumption mode of modern coastal residents in China(commonly known as “tail cutting”).The fifth part discusses the origin and transportation channels of Ellobium chinensis.From the ecological and distribution areas of the living Ellobium chinensis,the sources and related issues of the Ellobium chinensis unearthed from the Deshou Palace site were discussed.Studies on the living environment of living Ellobium chinensis show that the Ellobium chinensis unearthed from the Deshou Palace site should not be native to Hangzhou,and they are likely to be transported from the South China Sea through longdistance transportation.It reflects that during the Southern Song Dynasty,China had a transportation route to transport the preservation of marine products from the South China Sea to Lin' an(Hangzhou).At that time,people also mastered some food preservation techniques.The sixth part is the conclusion.The research contents of this paper are summarized,and the discovery and research significance of this batch of materials are summarized.It is pointed out that this study enriches people' s understanding of the eating customs of the royal palace in the Southern Song Dynasty,and also reflects the political influence and economic resource development of the Southern Song Dynasty.
